To oZZ' whom it may concern:

Be it known that L Grjossr. H. Dawson,

s citizen of the United States. and o rosicicni; of the city of Csmbricigc" in obs county of Middlcscx and State of Ii isssschusctts, have invented ccrvisin', new and usciiiii Zimprovcmcnts in on index-Cord Support; and I do hereby declare that the foilowmg is a full, clear, and exact cisscri iiiori of ifhs some, rsfcrsircs being iisci to me accompanying drawings andio iiio numerals of reference vniarkeoi thereon which form 9, part oi this specification.

This invention relates to visible index cards which are removsiiiy mounted. in s tray in overlapping relation with their lower edges exposed, and this invcriiion concerns itself primarily with ho supportmg means upon which the cords rcrnovabij" mounted My invention comprises iiic more} sbrnc tors, mechanisms and arrange-insist iiorcin after described and more psrticuisriy pointed out rind. defined in iris claims.

In ills accompanying cirowin illustrate csrasin preferred my invention and which once numcrsis refer co similar Figure-1 is frog'msiitsry from; piss view of s trsy iiiusirs bisg corcis moimtsci ihcroin iii ovorisppiog Wiibii tho lower J..

Figure 8 is s irsgmsiiisry cniargsd View of onoiiicr iiiociiiiccl form of supporting and spacing referring firs 1".ig5, it wiii be obssrvsoi that iii'c mounted upon fabric hingss n @GiIiRGCiJ-Qii is 3 of rscianguiar formation which siidzibly fit in guide channels ciformed, by the bent over edges 5 of the tray. When a plurality of cards are thus iy supportsd ins troy, ihey will overlap a distance equal to the Width-or height 02 thc spacing bars as is Wail-known in the art.

liziy invention relates primarily to the supporting means for the cards and comprises th fabric'ifiingc 52, which is prefer ably sizcd in order so impart sufiicient rigidity thereto and sfiampoci or pressed or creascd into a. card-attaching portion 6, a hinge portion '4'", and a bormimching portion 8 (Figure G) the csrdoritsching portion 5 being provided with lateral flaps 9 which src bent inwardly so: as to overlap 2L portion of the from; face to which they are secured by studs or eyelets 10 so that a notched card can readily be inserfcd thereunder for ihs purposs of engaging the studs or eycicis The borsttaching portion 8 is dssigncci to izo foidsd. over the top of the bar 3 and down the opposite side to some assent and firmly secured thereon by a metal cismp 11. Thc metal clamp '11 is originsiiy of iiihops having flanges of unsquoi length one flange being sobsisniciaiiy shorter toss silo height, fins distance from time so to the bottom of the bar 3, While siis other fian e being s trifle longer soon the of the bar. In attaching she mcisi clamp is is piscsd over the ifsbric, foidsoi psrtioiiy orouno the borwitii "ziici icing-sir flange on the rear sidc the port on of the ionger projecting boiow "tho bottom of tho bar 3 will then be ciiiripcci ovsr the iI OE'JiZQEH thereof as iridicoicd 11 in Fig. 3, firmly scouring iahc clamp $30 the box ogsinsi relative movement;

thereof, thus prcvcnting time fabric from being removed from or shift-sci on the bar. The shorter fiongc is adopted to extend only io iii-z top of the inclined hinge portion 7 so Limit the csrii Wiil have a tendency to hang beyond tho plains of the front face of the bar. The permanently combined hingicmsmbcr 2 and bar thus produce a very simpie and eiiicicnt card support.

Jihc imicx cord 1 is provided with a riovsijstcroi notch 1 or recess in each side scijoaism tho in (Figure 1), the botgom of tics iioiciiss ju cing spscsd sport. s distance so ivho dist-ones boo-Ween the studs .10;

and the card is adapted to be mounted or removed by flexing the same sutiiciently so that it can pass between the studs 10. When the card 1 is in mounted position upon its support, the flaps 9 will bear against the front face of the card and prevent laterai movement thereof as is obvious.

Instead of using a metal clamp to attach the hinge to the bar 3, the bar may be provided with a clamp slot 12 as shown in Figure 7 in which the upper margin of the hinge member may be securely and firmly clamped.

in some cases, a light channel-shaped bar made of folded metal may be used to ad- 'entage for supporting and spacing the the cards. in Figure 8, I have illustrated such a channel bar in which a sheet of metal is folded into channel-shape with the terminal margins 13 and 1st overlapping on the rear side of the web. The fabric hinge is adapted to be suspended from the upwardly extending margin 14 by a portion folded thcreorer and the marginal terminal 13 is adapted to be pressed or jammed against the \\(l) of the channel so as to permanently ancholathe'hinge member in place.

it is characteristic of my invention that the upper margin of the hinge member is permanently clamped or secured to a substantially rigid bar whereby the device may be secured in a tray. In the constructions illustrated, the margins of the hinge members are infoided in or about the bar, and the hinge projects from the front face of the bar that forms a lateral support theretor, but any means may be used for permanently securing the hinge member of the bar.

I am aware that numerous details of construction may be varied through a wide range Without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1.- In a card index system, a sized fabric hinge member having a card-attaching portion, a hinge portion extending at an an-.

gle to said card-attaching portion, and a barattaching portion extending at an angle to said hinge portion.

2. A hinged card support embracing a fabric strip, and means adjacent each end thereof adapted to engage the notched edges of a per end of said hinge member thereto, said hinge member being creased upon a line contiguous to a lateral face of said bar and extending at an angle thereto.

In testimony whereof I have hereunto subscribed my name in the presence of two suhscribing witnesses.
